[hibernate-dev] XSD question

Hi, There is an XSD question that I need some help suppose I want to design the xsd with following requirements: 1. element A has sub elements of B, C, D, E 2. sub elements should be not forced to be ordered ( so, choice :) 3. B --- maxOccurs = 1, minOccurs = 1 4. C,D -- maxOccurs = unbounded, minOccurs = 0 5. E -- maxOccurs = 1, minOccurs = 0 ------------------------- Best Regards, Strong Liu <stliu at hibernate.org> http://about.me/stliu/bio
